Re: [U-Boot] [U-Boot, v4, 42/66] rockchip: clk: rk3368: define DMA1_SRST_REQ and DMA2_SRST_REQ

On he RK3368, we need to temporarily disable security on the DMA engines during TPL and SPL to allow the MMC host to DMA into DRAM. To do so, we need to reset the two DMA engines, which in turn requires the DMA1_SRST_REQ and DMA2_SRST_REQ constants to refer to the appropriate bits in the CRU.

As the ATF correctly initialises security (and only leaves EL3 after doing so), this can not pose a security issue.
